Which alkali metal is isoelectronic with argon?

Potassium (K) is isoelectronic with argon because they both have 18 electrons.


Is K isoelectronic?

Potassium (K) is not isoelectronic with any other element in its neutral state. However, when it loses one electron to form a potassium ion (K⁺), it becomes isoelectronic with argon (Ar), as both have the same electron configuration of 18 electrons. Isoelectronic species have the same number of electrons and similar electronic structures, which in this case occurs when K loses an electron.


Is it true that the k2 ion forms commonly because it is isoelectronic with chlorine?

No, it is not true. The k2 ion, also known as the potassium ion (K+), forms because potassium (K) loses one electron to achieve a stable electron configuration. It is not isoelectronic with chlorine (Cl-) which gains an electron to achieve stability in its ionic form.


Does a positive Potassium ion have noble gas stability?

No, a positive Potassium ion does not have noble gas stability. Noble gases have a full outer electron shell, but a positive Potassium ion (K+) has lost one electron and does not have a full outer shell.
